Describe the bug After building the docker image and run with npm run test inside of docker container, got this error:

Error: EBUSY: resource busy or locked, rmdir '/app/test-results'

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! mapx-e2e@0.1.0 test: `dotenv-flow -- playwright test "report"`
npm ERR! Exit status 1

npm ERR! Failed at the mapx-e2e@0.1.0 test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

and inside of log, there is nothing useful

You can get around this issue pretty easily by defining outputDir in playwright.config to something like reports/test-results and then simply mounting the reports dir as a volume.

Yep I can repro. Turns out before 1.19 the test-results folder never actually was removed, so old results were piling in.

As of 2b55adaafa, we consider failure to clean up test results folder a fatal error. Let me see what we can do here.
